COMB.

SPECIFICATION forming part of Letters Patent No. 241,126,

dated May 10, 1881.

Application iiled IlIarch 25, 1881. (No model.)

To all whom it may concern:

Re it known that I, PATRICK II. DRAKE, of the city of New York, in the county ot' New York and State ot New York,have invented a 5 new and useful Improvement in'Oombs, which improvement is fully set forth in the following specitication and accompanying drawings, in Which- Figure l is a sectional side view of a comb 1o with myimprovement, and Fig. 2 is a sectional end View otl the same.

My device consists in the combination of a comb with -a permanent magnet, whereby is added to the friction of the said comb upon the scalp any physiological eiiect that may be de rivable from the inductive action of the said magnet.

In the drawings, Arepresents a comb made of hard vulcanized caoutchouc, known also by zo the names hard rubber 7 and ebonite.

B represents the magnet, which is inclosed in the back or body of the comb. This magnet is a piece of steel, made exceedingly hard by having been plunged int-o water or oil while 2 5 red hot. It is afterward rendered magnetic by placing it in contact with the poles ofa magnet or by inserting it in a helix or coil of wire properly constructed and circulating a current of voltaic electricity. Then a voltaic current 3o is used for the stated purpose the magnetization may be deferred until the said piece of hardened steel shall have been combined with the comb, when the completed comb may be placed within the said helix or coil.

At the time ot' forming the comb from prepared plastic caoutchouc the piece of hardened steel, before or after its magnetization is placed in position by embedding it in the said material, which, when solidified by subsequent steps 4o in the process of vulcanization, holds the said piece of steel Iirmly in place, the back or body of the Acomb being also strengthened and stift'- encd by the piece oi steel.

The comb may be made oi' some other suitable material in lieu ot' the said caoutchouc- 45 for example, common horn or the so-called celluloidand the said piece oi'hardened steel or magnet may be placed in a chamber or recess formed in such a comb by cutting or pressing; or the said piece of steel may be attached to 5o the outside of the comb by means of screws or rivets. In such case also it may serve to strengthen and stiften the body or back of the comb.

I am aware that it has been proposed to con- 5 5 struct a comb the teeth of which should be made of silver and zinc, or any other two appropriate dissimilar metals, arranged alternately and so as to i'orm a voltaic system or battery. Therefore I do not intend to lnake any claim 6o to the same.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The comb A, formed of any suitable ma- 65 terial, in combination with the permanent mag net B, substantially as shown and described.

2. The combination, with a comb, of a magnet inclosed in the body ot' the comb, substantially as described.

3. The combination, with a comb, ofa magnet extending parallel with the body oi' the comb, substantially as described.

In testimony whereof I have hereunto set my hand and seal in the presence of two sub- 75 scribin witnesses.

PATRICK II. DRAKE.

WILLIAM P. WARD, GEORGE F. Ross.
